To-all'whom it may concern:

Be it known that I, WILLIAM M. MoNnrLL, a citizen of: the United States, residin at Logansport, in the county of Cass and tate of ndiana, have invented certain new and useful Improvements in Soot-Blowers, of Whichthe following is a specification.

This invention relates to new and useful improvements in soot blowers, and more particularly to .soot blowers for boiler "furinaces As is well known, boiler furnaces are en- 'erall supplied with rows of water tu es, in w ich the water to be heated is circulated. Soot, carried by the ,products of combustion,-'collects upon these tubes and has a g It has been the practice to supply the boiler with what is termed a false plate,

-;which covers a number of openings in the fire wall of the combustion chamber. Through, these openingsv is introduced an open ended-pipe of considerable length connected with a source of compressed air supprly, the purpose being to blow the soot om the: tubes This operation is exceed-- ingl-ytedious and where a large battery of boilers is used, requires the undivided at- In order to facilitate the operation of blowing the sootfrom the lines, I have providedin the fire wall of the combustion chamber, a. rotatable tubular memberprovided with a number of tubular arms, having openings therein. .To the tubular mem- ..ber,is introduced compressed air or steam which, passing, outthrough the openings n.

thearmsoperates to blow 'the soot from the tubes, meansbeing rovided whereby the tubes may be oscillated within the furnace.

Meansareg also provided to protect the tube the action of theproducts of combustion.

, urther obj ects be obvious, during the -course, of the following discussion:

In the drawings,.wherein tor the purpose 5 ,of: illustration is ,Shbwn a preferred embodiment. of mydevice,=and in whichlike numorals are employed to designate l ke parts rcug tthesan e,

Eigure 1 a side elevat10n,,,partly 1n device in position in the boiler and illus- .trating the application of the protecting tile, and,

tendency to insulate the tubes from the heat and consequently to lower the heat of the boiler.

tical opening 11, in which is arranged a tubular member 12. The tubular member 12'i's closed at its lower end and provided with a reduced extension 13, which extends through an opening 1 1, formed in a casing 15.

Extension 13 is "provided from one side thereo.f, with a rack 16, for a purpose hereinafter toappear. Upon the lower end of the extension. 13 ismounted a miter gear 17,. .A shaft. 18 is suitablyjournaled in-sthe casing. 15 and hascsecured thereto amiter gear 19, meshing with the gear 17. One end of theshaftlS extends outside the casing, and .is provided with means 20 for; rotating the same. Mounted upon the shaft 18 is la second shaft-21, having secured theretoa pinion 22 meshing the'rack. 16 on the extension-13, The outer end of theshaft 21 'is provided with means for rotating the same,23. r

Surrounding the tubular member 12. adjacent to the up er end thereof uisa sleeve 24,- provided wit radialarms 25, which are embedded in the fire wall. This sleeve. positions theupper end of the tubular member. The extreme upper end of the tubular memher is provided with an enlargement 26,

forming the male member of ab'ell 'slip joint.

Mounted above-the tubular" member .is an L prov ided upon its'jupper, end with a flange 28. The lower end of the L is expanded either at right angles as shown in Fig. 1, or downwardly as shown in Fig. 4.,

to form. the female. member 29 of the, slip is provided upon one side" thereof with plurality of allned sockets 80f Mounted in thesesockets are tubes 31 having their outer ends "32'clds'ed bygabap or thelike- These tubes are provided througliout' their length with upper and lower openings and 't'hetubes pendin flan pleted,

are arranged intermediate adjacent'rows'of the boiler tubes 33. a

' Embedded inthe wall of the combustion chamber are angular fire tiles 34, the dees 35 of these tiles being spaced from t e waas clearly shown in F g, 6. These tiles are so spaced"vertically "as. to leave between the bottom of one tile and the top ofthe next, a'space sufficientftgreceive the tube 33. The fianges35.";of'the tile have their faces spaced sufficiently 'far from the fire wall to afford a recess arre ting the tubes therein. If desired, these recesses may be formeddi'rectly in the wall of the furnace. Thes'pace's and'i'eces'ses formedin the wall communicate with the verticalopenin 14 he operation of my device isas follows:

The L 27 is connected with a suitable source-of compressed air or steam supply,

the compressed-air or steam being delivered by the tubes 31 through the openings 32 thereof. 13' means of the shaft 18, the'tubular mem er is oscillated, swinging-the tubes as suggested, by the varying posltions shown in F1 .1 "It will be clearly seen that the tube wil cover a comparatively large area ofthe interior of the boiler, blowing down the soot from the boiler tubes. When the operation of cleaning the tubes is comthe tubesare swung tothe position shown in Fig. 6. The shaift 18 is now rotated and the tubular member elevated, so that the tubes are placedbehind the dependin flanges 35 of thepr'otectingtiles 84.

i is" to be understood that the formbf my invention herewith shown and described is to betaken as a preferred example'of the same, and that various changesin the shape, size, and arrangement ofpartsl'ma be" resortedto without departing from t e spirit of the inventionfor the 'scope 'fof the sub joined claims :Having thus described my inventiomflI claimi Q'Q 1.
